What is the function of the stomata?

The stomata controls the flow of gases in and out of the leaves.

Explanation:

The opening and closing of the stomata controls gas flow in leaves. This controls is necessary to prevent excessive loss of water as vapour from the plant body via transpiration. Usually stomata opens in the day and closes in the night. Each stoma or stomatal wall is flanked by two bean-shaped guard cells, the only epidermal cells with chloroplasts. The wall of the guard cells next to the pore are thicker than those adjacent to the epidermal cells. Here,,the thicker wall cannot stretch as much as the thinner walls.

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
